Abstract
Procedimiento de blanquear fibras de celulosa natural y regenerada y de productos fabricados con ellas con clorito y peróxido caracterizado porque el tratamiento del material con clorito y peróxido se realiza en un solo baño por ejemplo blanqueando previamente con clorito ácido y terminando de blanquear con adición de peróxido y estabilizadores en el baño alcalino o procediendo en orden inverso.Procedure of bleaching natural and regenerated cellulose fibers and products made with them with chlorite and peroxide characterized in that the treatment of the material with chlorite and peroxide is carried out in a single bath, for example, previously bleaching with acid chlorite and finishing bleaching with the addition of peroxide and stabilizers in the alkaline bath or proceeding in reverse order.
